Did you create the index before or after adding those settings? It'll
only affect indices created afterwards.

Actually I tried both. I tried after changing the config and
restarting the node (recovers the index from the gateway), did not
work, even for data added after the change.
I also tried after deleting the index using the REST API and I also
tried after wiping the indices and gateway directories and restarting
the node.

The configuration looks good (btw, when you create an index, you still need
the index "prefix" in the settings provided). I tried it locally and I see
that it gets added. Can you gist a sample that shows it does not work for
you?

Well, in this case, I am not using the API Create Index. I am just
starting to directly add documents which triggers the index creation
on the first item. This is where I am hoping that it will pickup the
default analyser redefinition in the elasticsearch.yml config.

Is this the problem? Do I absolutely need to use Create Index and pass
it the analyzer config?
